yeah, that would be a good thing to know. The manual says to change the "screen", but doesn't mention where it's at. From looking at other kymco scoots, it looks like they use inline filters. Just from looking at this photo this looks similar to others i've seen. I'd have to take my seat off to double check. In your pic, right in front of the tank in the center it looks like an inline filter. Maybe right.... maybe wrong.
